EU Framework 5 Project LCOS4LCOS

To design a low cost projection TV display including an innovative
high illumination optical engine based on a single Liquid Crystal
on Silicon (LCOS) chip.

By combining the director modelling, optical modelling and a commercial
ray tracing simulation package the optical properties of the whole
illumination, projection and optical engine system can be predicted.
